Abstract

L'invention concerne la fabrication de pâte à papier à haut rendement à partir de copeaux de bois. Le procédé consiste à traiter successivement les copeaux, avant défibrage, par une solution contenant au moins un agent réducteur, puis par une solution alcaline de peroxyde d'hydrogène. Application à la fabrication de pâtes à papier ayant un degré élevé de blancheur et de bonnes caractéristiques mécaniques.
